Sanitary mixing valve

ABSTRACT

A sanitary mixing valve for controlling the flow and mix of hot and cold water supplied respectively from a hot water inlet and a cold water inlet. The valve includes a valve body coupleable to the hot and cold water inlets and having a water outlet. A disk packet is supported on the valve body and includes a control disk. The control disk includes a mixing chamber for receiving a mix of the hot and cold water. A temperature-dependent control element is positioned on the control disk to directly measure the temperature of the mixed water in the mixing chamber. The temperature of the water emerging from the water outlet is regulated according to the measured temperature.

The invention refers to a sanitary mixing valve with thermostaticregulation, with an actuation element, with a stationary valve seatdisc, with a disc packet displaceable on the valve seat disc to controlthe flow and with a temperature-dependent control element, wherein thevalve seat disc has a cold water inlet port and a hot water inlet port,wherein the disc packet consists of a lower guide disc, an upper guidedisc and a control disc which is provided between the lower guide discand the upper guide disc, wherein the lower guide disc and the controldisc have passages communicating with the cold water inlet port and thehot water inlet port of the valve seat disc, and the upper guide dischas pressure compensation chambers communicating with the passages ofthe control disc, and wherein the control disc can be set for thepurpose of temperature control by means of the actuation elementrelative to the guide discs to a starting position which determinestemperature and, for the purpose of temperature regulation, can becontrolled by means of the temperature-dependent control element.

In the known sanitary mixing valve, on which this invention is based(cf. DE-OS 35 25 052), the temperature-dependent control element islocated essentially outside the disc packet which effects flow andtemperature control and regulation in the water chamber for the emergingmixed water, although it acts on the spring-loaded control disc locatedbetween the guide discs of the disc packet and forms a functional andstructural unit with the disc packet. This goes to prove that thetemperature control via the temperature-dependent control element isrelatively slow.

The object underlying this invention, is therefore to improve the knownsanitary mixing valve, on which this invention is based, in such a waythat the control disc is more quickly and sensitively controlled via thetemperature-dependent control element so that the preset mixed watertemperature is kept constant without perceptible fluctuations.

The sanitary mixing valve according to this invention, in which valvethe object deduced and explained above is achieved, is characterized inthat in the control disc at least one mixing chamber is provided whichcommunicates with the passages of the lower guide disc and/or with thepressure compensation chambers of the upper guide disc and in that thetemperature-dependent control element is located in the mixing chamberof the control disc and/or in a cavity of the control disc which cavitycommunicated with the mixing chamber and in that partial flows of thecold water and the warm water enter into the mixing chamber and themixed water flows around the control element. Preferably, one mixingchamber communicating with the passages of the lower guide disc and onemixing chamber communicates with the pressure compensation chambers ofthe upper guide disc are provided in the control disc, the two mixingchambers lead into a cavity of the control disc and thetemperature-dependent control element is placed in the mixing chambersand/or in the cavity of the control disc.

In the sanitary mixing valve according to this invention at least apartial flow of the cold and hot water is mixed in the control discitself and the mixed water is directly brought to thetemperature-dependent control element over a short path so that in thecase of deviations of the mixed water temperature from the preset mixedwater temperature, a control of the control disc relative to the twoguide discs is immediately effected, initiated by the control element.

In the following, the invention and advantages achieved by the inventionare explained in connection with an exemplary embodiment reproduced inthe drawing: the drawing shows in:

FIG. 4 schematically the disc packet with the realized water pathways,which packet consists of the lower guide disc, the control disc and theupper guide disc.

To begin with, the sanitary mixing valve depicted in FIGS. 1 and 2 has avalve body 10 with a water outlet 11 and an actuation element with anactuation lever 12 and an actuation handle (not shown) mountable on theactuation lever 12. A cartridge housing 13 is inserted in the valve body10. Above the cartridge housing 13 is a valve body cover 14 which issecured in the valve body 10 by means of a retaining ring 15. The valvebody cover 14 has an actuation opening 16 through which the actuationlever 12 passes. An O-ring 17 is provided at the foot of the actuationopening 16 so that the actuation lever can be moved in a sealed manner.A hot water inlet 18 and a cold water inlet 19 are attached on thebottom of the valve body 10. Passages in the bottom of the cartridgehousing 13 corresponding to the passages in the bottom of the valve body10 which receive the hot water inlet 18 and the cold water inlet 19.Seals 18' and 19' are inserted into the passages provided in the bottomof the cartridge housing 13.

Secured to the bottom of the cartridge housing 13 is first a valve seatdisc 20 with a hot water inlet port 21 and a cold water inlet port 22. Adisc packet is placed on the valve seat disc 20, which disc packet isdisplaceable as a whole with respect to the valve seat disc 20 by meansof the actuation element, i.e. by means of the actuation lever 12, forthe purpose of flow control. The disc packet consists of a lower guidedisc 23, an upper guide disc 24 and a control disc 25 placed between thelower guide disc 23 and the upper guide disc 24. The lower guide disc 23has passages 28, 29 which communicate with the hot water inlet port 21and the cold water inlet port 22 of the valve seat disc 20 and to whichin the control disc 25 passages 33, 34 are associated so that thepassages 33, 34 of the control disc 25--depending on the position of thedisc packet with respect to the valve seat disc 20--can also communicatewith the hot water inlet port 21 and the cold water inlet port 22 in thevalve seat disc 20. Furthermore, the upper guide disc 24 has pressureconsumption chambers 36 which are associated to the passages 33, 34 ofthe control disc 25. The pressure compensation chambers 36 of the upperguide disc 24 can--depending on the position of the controldisc--communicate with the passages 33, 34 of the control disc 25 andthe passages 28, 29 of the lower guide disc 23, and--depending on theposition of the disc packet with respect to the valve seat disc 20--withthe hot water inlet port 21 and the cold water inlet port 22 in thevalve seat disc 20. Finally, a temperature-dependent control element 39is provided as a further structural element necessary for operation.

As already explained, the control disc 25 can be set for the purpose oftemperature control by means of the actuation element, i.e. by means ofthe actuation lever 12, relative to the guide discs 23, 24 to a startingposition which determines temperature. In addition, the control disc 25can be controlled by means of the temperature-dependent control element39 relative to the guide discs 23, 24 for the purpose of temperatureregulation.

Hence, both flow control and temperature control and regulation areeffected in the sanitary mixing valve in question. The flow control iseffected by a linear displacement of the whole disc packet relative tothe valve disc 20, namely by means of the actuation element and thus bymeans of the actuation lever 12. The temperature control is alsoeffected by a linear displacement, namely by a displacement of thecontrol disc 25 relative to the guide discs 23, 24, again by means ofthe actuation element and thus by means of the actuation lever 12.Finally, the temperature regulation is also effected by a lineardisplacement, namely as in the case of the temperature control by alinear displacement of the control disc 25 relative to the guide disc23, 24, however, by means of the temperature-dependent control element39.

According to the invention, at least one mixing chamber communicatingwith the passages of the lower guide disc and/or with the pressurecompensation chambers of the upper guide disc is provided in the controldisc and the temperature-dependent control element is located in themixing chamber of the control disc and/or in a cavity of the controldisc communicating with the mixing chamber. In the case of therepresented exemplary embodiment, as in particular FIGS. 1, 1a, 3a and3b show, a mixing chamber 35 communicating with the passages 28, 29 ofthe lower guide disc 23 and a mixing chamber 35 communicating with thepressure compensation chambers 36 of the upper guide disc 24 areprovided in the control disc 25, the two mixing chambers 35 lead into acavity 36 of the control disc 25 and the temperature-dependent controlelement 39 is located in the cavity 32 of the control disc 25. As forthe rest, a textile material which is indicated in FIG. 2 only, isinserted in the mixing chambers 35 which serves to better mix the coldand hot water on the one hand, and leads to a noise reduction on theother.

In the represented exemplary embodiment, the lower guide disc 23 and thecontrol disc 25 each have four passages numbered 28/29 and 33/34respectively, and each group of two passages 28 and 29 of the lowerguide disc 23 communicate with the hot water inlet port 21 and the coldwater inlet port 22 of the valve seat disc 20, respectively. Inparticular, the lower guide disc 23 has, on the side facing the valveseat disc 20, inlet slits 26, 27 associated to the hot water inlet port21 and the cold water intel port 22 of the valve seat disc 20, and fromthe outer ends of each inlet slit 26, 27 emerges a passage 28, 29respectively (cf. FIG. 3b). The passages 28, 29 of the lower guide disc23 have, on the side facing the control disc 25, enlargements 30 (cf.FIG. 3a) which communicate with the lower mixing chambers 35 of thecontrol disc 25. In the represented exemplary embodiment the lower guidedisc 23 and the control disc 25 each have four passages 28/29 and 33/34.Therefore, the upper guide disc 24 has, on the side facing the controldisc 25, four pressure compensation chambers 36, namely pressureconsumption chambers 36 which are associated to the four passages 33, 34of the control disc 25 (cf. FIG. 3b).

Furthermore, in the represented exemplary embodiment of a sanitarymixing valve according to the invention, the lower guide disc 23 and theupper guide disc 24 each have, on the sides facing the control disc25--further--pressure compensation chambers 37 for partial flows of thecold and hot water, and the pressure compensation chambers 37 areprovided on the outer delimiting edges of the lower guide disc 23 andthe upper guide disc 24 and are open to the outside.

In the represented exemplary embodiment, the temperature-dependentcontrol element 39, as particularly FIGS. 1 and 1a show, is cylindricalin shape and has a piston 40, and the control disc 25, as FIGS. 1a, 3aand 3b show, is U-shaped, with the arms 31 of the U bordering the cavity32 and the passages 33 and 34 as well as the mixing chambers 35 beingformed in the arms 31 of the U.

It has initially been mentioned that in the sanitary mixing valveaccording to the invention the lower guide disc 23, the upper guide disc24 and the control disc 25 form a disc packet. As is shown in FIG. 1a,the lower guide disc 23 and the upper guide disc 24 are clampedtogether--by means of bolts 51 penetrating passages 50 in the guidediscs 23, 24--using interposing spacer sleeves 52, with the length ofthe spacer sleeves 52 ensuring the space between the lower guide disc 23and the upper guide disc 24 which space is necessary for thedisplaceability of the control disc 25.

As regards the temperature-dependent control element 39, it isadditionally to be pointed out that, as FIGS. 1 and 2 show, a shackle 41overlapping the disc packet is provided, and clamped between the twoarms 42, 43 of the shackle are a return spring 44, the control disc 25and the temperature-dependent control element 39. In detail, the returnspring 44 presses against the arm 42 of the shackle, the control disc 25against the return spring 44 and the temperature-dependent controlelement 39 against the control disc 25 on the one hand and--with itspiston 40--against the arm 43 of the shackle on the other, to be moreprecise against an adjustment screw provided at the arm 43 of theshackle. The shackle 41 can be displaced on a control cage 45 whichforms a frictionally engaged unit with the disc packet. For thispurpose, a control cam 46 of the actuation lever 12 engages in acorresponding recess in the shackle 41, with the control cam 46 of theactuation lever 12 having an eccentric element so that a rotary motionof the actuation lever 12 and thus a rotary motion of the control cam 46is converted into a linear displacement of the shackle 41. The controlcam 46 of the actuation lever 12 and the associated recess in theshackle 41 are such that a so-called "comfort zone" is produced, bymeans of which relatively large rotations of the actuation lever 12result in only a small displacement of the shackle 41 and therefore in asmall change in the temperature setting.

In the sanitary mixing valve according to the invention, a partial flowof the cold water and of the hot water is mixed in the control disc 25itself, to be more precise in the mixing chambers 35, and the mixedwater is directly brought to the temperature-dependent control elementover a short path so that in the case of deviations of the mixed watertemperature from the preset mixed water temperature, a control of thecontrol disc 25 relative to the two guide discs 23, 24 is immediatelyeffected, initiated by the control element 39.

In the represented exemplary embodiment of the sanitary mixing valveaccording to the invention the lower guide disc 23 and the upper guidedisc 24 have, on the sides facing the control disc 25, pressurecompensation chambers 37 for the partial flow of the cold and hot water,i.e. have pressure compensation chambers 37 which do not communicatewith the mixing chambers 35 of the control disc 25. Thus, if the crosssections have the appropriate dimensions, it is possible to fix theratio of the partial flow of the control and hot water which passes intothe mixing chambers 35 of the control disc 25 to the partial flow of thecold and hot water which does not pass into the mixing chambers 35 ofthe control disc 25, and thus to determine the regulationcharacteristics. As for the rest, all partial flows of the cold and hotwater naturally come together in the water chamber 38 of the sanitarymixing valve according to the invention. In the water chamber 38, allthe supplied water is again mixed before it leaves the sanitary mixingvalve via the water outlet 11.

Water flows through the sanitary mixing valve according to the inventionas follows:

Pivoting movements of the actuation element and thus the actuation lever12 in the plane of the water outlet 11 result in regulation of thequantity of water flowing through the mixing valve, by the fact that thedisc packet is displaced on the valve seat disc 20 because of thefrictional coupling with the control cam 46 of the actuation lever 12effected by the control cage 45. In this process, the inlet slits 26, 27of the lower guide disc 23 work together with the hot water inlet port21 and the cold water inlet port 22 of the valve seat disc 20, so that acorresponding quantity of water can flow through the mixing valvedepending on the position of the disc packet with respect to the valveseat disc 20.

Temperature control is effected by rotating the actuation element andthus by rotating the actuation lever 12, with the rotation of theactuation lever 12 being converted by the control cam 46 into a lineardisplacement of the shackle 41 and thus a linear displacement of thecontrol disc 25 relative to the guide discs 23, 24. The relativeposition of the control disc 25 with respect to the guide discs 23 and24 determines the mixed water temperature.

Partial flow of the cold and hot water enters into the mixing chambers35 of the control disc 25 which face the guide discs 23, 24. From themixing chambers 35, the mixed water flows around thetemperature-dependent control element located in the control disc 25.The temperature-dependent control element 39 controls the position ofthe control disc 25 with respect to the guide discs 23, 24 by means ofthe piston 40 which responds to changes in temperature.
